GRE Subject Test Scores
In calculating reported scores for the
traditional paper-and-pencil GRE Subject Test, the number of questions answered
correctly is adjusted according to the difficulty level of the questions on the
test form. Thus, the same number of correct responses on different test forms
will not necessarily result in the same reported score.
In paper-and-pencil tests, the differences in difficulty among test forms are
relatively small and are adjusted through a process known as score equating. The
number of questions answered is also figured into the calculation of the
reported score because it limits the number that can be answered correctly.
Scoring of the tests is a two-step process.
- First, a raw score is computed. The raw score is the
number of questions you answered correctly minus one-fourth the number of
questions you answered incorrectly.
- The raw score is then converted to a scaled score
through a process known as equating that accounts for differences in
difficulty among the different test editions. Thus, a given scaled score
reflects approximately the same level of ability regardless of the edition
of the test that was taken.
Score Scales for the GRE Subject Test
One total score is reported on a 200 to 990 score scale, in ten-point
increments, although the score range for any particular test is usually smaller.
Subscores are reported for the biochemistry, cell and molecular biology;
biology; and psychology tests on a 20 to 99 score scale, in one-point
increments, although the range for any particular test subscore is usually
